Just food for thought, a CRJ 700/900 generator output is 115VAC @ 40KVA (115 x 40,000 = 4,600,000) = 4.6 megawatts.

but hey, turbo-props are coming back!

Been a while since I did electrical math, but if the gens in a CRJ are 3 phase, that 40kva would equate to about 200 amps each. A bit less than that for single phase. Puts it around 18,000-23,000 watts per gen. This is just spit balling a generic power factor into it.
